Your the one that just turned this into a pissing contest, all I said was the new design works better since it runs quieter and smoother. I don't gave a rats ass what you use. and by the was I was a mechanic for over 30yrs.

You haven't offered ONE BIT of useful or helpful information in this thread or on this topic *anywhere*.
In fact the only so-called "information" you have given out is WRONG.
The GM Harrison HR6 automotive A/C compressor, (just like its predecessor the DA6 and it's follow-on compressor the HR6E), has 3 pistons, NOT 6 as you claim.

Want have a pissing contest about that too? Fine, just show us YOUR parts book or a schematic or *anything* of this GM Harrison HR6 compressor that you claim to have 6 and now 10 pistons. I would like to see it.

Here is the ACTUAL parts break down of the DA6, HR6 and the HR6E:

Here is RWDPLZ's teardown WITH PHOTOS comparing both the DA6 and the GM Harrison HR6

You have done NOTHING in this thread to offer ANY real helpful, correct information.
NOTHING to answer sricka01's questions or offer him any actual help.

Just a pissing contest and WRONG information.

No wonder a lot of long time members here that have gone to the trouble to do this kind of work, take photos, document procedures and share it freely with others are LEAVING this forum.

It is now loaded with a lot of jackwagons that KNOW NOTHING, CONTRIBUTE NOTHING and argue with everyone.

Now I see why no one responds to you and you can add me to the list since your opinion is always right no matter what. Sorry if I devalued your stock in 4 seasons. Go find some one else to fight with since this is the last response you'll get from me. I'll stick With new compressors, you can stick with the remans.

Great, but I still want to see this mythical 10 cylinder Harrison HR6 compressor of yours.

Try to put a very small dab of silicone or RTV sealant on one side of the switch on the outside of the plastic housing where it will NOT interfere with the metal to metal contact of the plug. Connect it back up and let it set for a few hours to cure. Make sure both surfaces, (switch and plug), are CLEAN and OIL FREE. Wipe off with alcohol before applying the sealant.
It should only require a tiny spot, approx. the size of a #2 pencil eraser, or less to hold the plug in place and still be able to pull it off later if the need arises.





Thank you very much Randye! I will try this RTV method. Very simple idea!

Randye, I looked up old receipts for my two 88 GT's. The first compressor was "compressor works" from Autozone part #620248.
I don't remember the unit having any ICE32 in it, it was bone dry. CompressorWorks is owned by FourSeasons anyway.
In the description, they state it has 10 cylinders and also uses PAG46. Well I used PAG150 (I hope that won't be an issue.)
http://www.autozone.com/coo.../841638_145609_3513/
Each unit is assembled with ICE32 lubricant to reduce internal friction promoting enhanced system performance and longevity
Our 10 Cylinder design runs quieter and more efficient than the original equipment 6 Cylinder design It also incorporates dowel pins to prevent case twisting - a common source of leaks in the original equipment design
Each unit is individually leak, vacuum and pressure tested prior to packaging to ensure leak free performance
Uses PAG 46.

There's a good rebate on this model right now:
Rebate details: AUTO1168 AutoZone Rebate. Purchase one New Compressor, one Accumulator or Receiver-Drier and one Expansion Device between 06/30/15 – 07/27/15 and receive a $40 AutoZone Gift Card.

Autozone probably has a really bad description. I guess it really doesn't matter what compressor it is considering both freeze me out to 38*. All the posts from Randye, RWDPLZ, and Marvin were extremely helpful in the teardown, flush, HNBR oring explanation about captured/noncaptured, vacuum, and charging. Saved me alot of money and gave me new tools like curved wrenches, manifold gauges, and vacuum pump from HF.


I checked CompressorWorks website and they only list NEW category for HR6 even though AZ says its reman'd.
http://eaccess.smpcorp.com/ecataloglite/CWI/
They also say to use PAG150. I searched all over and everywhere for GM HRx version, to use PAG150. So right there, AZ website has two wrong details.

Yes they do have bad descriptions. Here in the Southeast the AutoZone stores and Advance Discount Auto stores have merged at the corporate level, and although they still have separate stores, they maintain common warehouses and it appears they have the same fools running their websites. I have noted a great many descriptions for products applied incorrectly on both websites. I never use their website information as authoritative for anything more than their own part number and a price.

I'm happy if I have been even marginally helpful and I hope the RTV works for you. It's not the optimal solution, but then compressor switch plugs aren't something one normally disconnects regularly.

I made another Air Conditioning parts post a while back with more switch information, pictures, and part number cross references

http://www.fiero.nl/forum/Forum2/HTML/000652.html





The black piece on the clutch cycling switch is removable, it protects the terminals in shipping.

However all HR 6 compressors do not have a high pressure switch. The 4.9L version comes to mind. For these applications a switch on an external switch port can be used.




The 4.9, as installed in a Fiero by TFF, does not utilize any pressure switches. At all. Mine worked fine (for probably 8 years) right up until it didn't.
Coming back from Indy, I blew out a high pressure hose at 80 MPH. Was pretty spectacular. Thought I had blown an engine, based upon the noise and smoke.
When I rebuilt the A/C system (complete flush, and new accumulator and compressor) I added a high pressure switch. I did not add the low side switch, as it seemed to be redundant to the pressure/cycling switch in the front. (Yes... I understand the difference, and am willing to put up with it.)
